Patented July 14, 1931 UNITED STATES PATENT OFFICE ALLAH A. ADAMSON, or ROCHESTER, NEW Yomr; AssIGNomrYMEsNn ASSIGNMENT& 'ro AUTOKRAI'T BOX CORPORATION, or LIMA, OHIO, A CORPORATION OF DELAWABE p BOX LID Application filed March 18, 1929, Serial No. 347,&65.

The present invention relates to boX lids and more particularly to the type made of laminated paper board; an object of this invention is to provide a construction which will have the desired strength while being able to utilize cheap paper stock.

To this and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described: the novel features being pointed'out in the appended claims.

Fig. 9 is an enlarged fragmentary sectional view of one edge of the cover.

The use of laminated paper stock for the making of cigar box lids is becoming more general With the increase in the cost of 1uInber, but in order to obtain a lid which will be in any sense effective, the highest grade of paper board stock must be einployed and even then the lid is not sufficiently strong but bends under certain conditions, due to the slipping of the layers or laminations of the stock one upon the other. This slippage increases with the decrease in the grade of the paper stock. It iscommon to apply to lids of this type, labels, edging or inside and outside linings or wraps, but these are made of paper stock having no material strength and usually light in color in order that the advertisements or ornamentations thereon will be properly displayed. These labels, edging, inside or outside lining or Wraps do not prevent the slipping of the layers or laminations as they break under bends in the lid. The Weakest portions of the lid are adjacent its front and side edges and this isVWhere the greatest slips in the layers or laninations take place, and this is also where the edging is usually arranged so that the latter, being nade of a readily rupturable material, breaks with the shifting of the layers or laminations of the lid. i

This invention over-comes the shifting of the layers or laninations in a lid made-of laninated paper board and protects the ornamental edging or bordel' as well as prevents the bending of the lid under' ordinary stresses.

'In the illustrated embodiment of the invention, 1 indicates a laminated paper board which may be of very cheap stock. A 'sheet 2 of tough paper such as is known in the trade as kraft paper is adhesively secured to one side of the lid to cover the entire side, this sheet having flaps or extensions which ,are bent around and adhesively secured to the front and side edges of the lid and also extended over and adhesively Secured to the other face of the lid as at 3. Another sheet 4: of tough paper, such as kraft paper, is adhesively secured over the other face of the lid and has three of its edges provided with flaps or extensions 5 which are passed about the front and side edges of the lid and onto the other face of the lid,so that one of the two sheets overlaps the other not only at the front and side edges but also in proximity to said edges on both sides of the lid. This strengthening prevents theslipping of the laminations of the paper board and strengthens the latter throughout its body. The hinge or rear edge of the lid is Secured and does not require any strengthening. i

The kraft paper is a colored paper and is not desirable according to the trade conditions for exposure so that the labels, ornamentation and other matter cannot be printed thereon. For this reason, the strengthened lid is covered on the outside by a paper wrap 6 which may be ornamented or printed' to meet trade conditions and on the inside by a paper liner 7 which acts as a label, both being made of cheap paper, and one,

in this instance, the wrap 6 having flaps or extensions 8 which are passed about the front and side edges of the lid and onto the inner face where it is covered by the liner 7.

It has been found that it is more economical to cover a cheap laminated paper board with tongh kraft paper on both sides than to use high grade paper board, and in addition, a much stronger lid structure is obtained.

What I claim as my invention and desire to secure -by Letters Patent is:

1. A lid or cover for boxes, formed of laminated paper board and having two sheets of tough paper covering theentire area .of and adhesvely Secured to opposite faces of the lid, each sheet having adhesively Secured portons turned about the front and side edges of the lid and eXtending onto the opposite face of the lid, the turned portons -of .one sheet being beneath the other sheet.

2. A lid or cover for boxes, fornied of laniinated paper board and having two sheets of tough paper covering 'and adhesively Secured over opposite faces of the lid, each sheet having adhesively Secured `portions turned about the front and side edges of the lid and extending onto the opposite face of the lid, the turned portions of one sheet being beneath the other sheet, a liner covering the inner face of the lid, and a wrap coverng the outer face of the lid, one of said last two named elements having extensions bent about the front and side edges of the lid.
